The learner deliberately gave incorrect answers and acted out a prearranged script. For example, at 150 volts, the learner would cry out, “Experimenter, get me out of here! I won’t be in the experiment any more!” At 270 volts, the learner would scream in agony. When the shock reached 350 volts, the learner would fall silent. If the teacher wanted to stop the experiment, the experimenter would insist that the teacher continue, using such statements as “The experiment requires that you continue” and “you have no other choice; you must go on” (Milgram 1975:19-23)
